Radar bullet is a special type of bullet the main use of radar bullet is to find landmines without setting foot into the ground .This consists of firing a special bullet into ground from a helicopter which could pinpoint buried landmines. Anti -personal mines claims seventy new victims every day. This weapon is particularly cruel on children whose bodies being smaller and closer to the blast are more likely to sustain serious injury. The severe disabilities and psychological trauma that follow the blast mean these children will have to be looked after for many years. Technologies are used for landmine detection are: Metal detectors--- capable of finding even low-metal content mines in mineralized soils. Nuclear magnetic resonance, fast neutron activation and thermal neutron activation. Thermal imaging and electro-optical sensors--- detect evidence of buried objects. Biological sensors such as dogs, pigs, bees and birds. Chemical sensors such as thermal fluorescence--- detect airborne and waterborne presence of explosive vapors.
